Ren returns to the town of his childhood, Kaminohara. 
Strangely, Ren is unable to recall any memories of the town. 
Meanwhile, his smartphone installs a mysterious game called Monster Strike — heralding the start of a desperate battle!
But even though I lived here,
I don't remember anything from then.
Obwohl ich hier lebte,
habe ich keine Erinnerungen daran.
A pesar de que viví aquí,
no recuerdo nada.
Aunque vivía aquí,
no tengo recuerdos.
Mais je n’en ai aucun souvenir.
Apesar de ter morado aqui,
não tenho memória disso.
